attempted repair on a laptop a few months ago - similar problem - the power
supply connector had become internittent
to get that laptop appart meant removing all the visible screws - there were
a couple on the botton that let you take off the mousepad - and then you had
to remove daughter boards the cd the harddrive and there was an aluminium
heat sink attached to the processor with 4 screws and once you got down to
the motherboard there were lots of threaded pillars to remove all different
sizes ( i labelled them a , b, c etc with cd writing pen to make sure i got
them all in the right possitions) then the motherboard comes off and you can
resolder the ps connector -- on my laptop the intermittent ps connection had
blown the onboard power supply electronics which were all surface mount and
i gave up at this point and returned the laptop to the customer -
dissasembly and reassembly took about 3 hours - not something ill attempt
again on a no repair no charge basis
good luck
oh btw there were some screws that were only visible once you had removed
small circles of plastic covering them
